Abstract
An entry door lock system includes an energy storage device (27) to permit unlatching if unlatching movement of a door handle occurs before the latch has been unlocked. The device (27) is passive if unlocking occurs before unlatching movement of the door handle. The invention avoids the need for repeat movement of the door handle in cases where unlocking follows initial door handle movement.
